Integrated BioPharma manufactures vitamins, nutritional supplements, and herbal products through its primary operating subsidiary, Manhattan Drug Company (MDC). MDC is a contract manufacturer — customers bring their own formulations and branding, and MDC produces the finished product. Customers are primarily large nutritional supplement brands and MLM companies. The business is highly concentrated, with two customers, Life Extension and Herbalife, together accounting for roughly 84% of consolidated net sales. Revenue is driven by customer order volume and per-unit manufacturing prices, with no minimum purchase commitments in place, making revenue highly dependent on continued orders from this small customer base. Raw material costs are a key input; MDC sources vitamins, minerals, herbs, capsules, and packaging from multiple suppliers, generally on a purchase order basis without long-term contracts. Integrated BioPharma operates a secondary segment covering warehousing and fulfillment services and raw material distribution, though these are not significant revenue contributors. The company is a niche, small-scale operator with roughly 153 employees.
